Title
(EN) APPARATUS FOR MICROBIOLOGICAL TESTING
(FR) APPAREIL POUR ESSAIS MICROBIOLOGIQUES
Abstract
(EN)
Apparatus for performing a plurality of microbiological tests comprising a layer of agar or other nutrient gel filling a plurality of channels which communicate with a common region from which the apparatus may be charged with liquid agar prior to use; characterised in that indicia are provided adjacent said channels to permit a direct visual measurement of the effect of the test substance on the growth of a microorganism on said agar, when said test substance has been allowed to diffuse along said channel from a determined point of application to form a concentration gradient of said substance along said channel.
(FR)
Appareil pour effectuer plusieurs essais microbiologiques, contenant une couche d'agar ou autre gel nutritif remplissant plusieurs canaux qui communiquent avec une région commune à partir de laquelle l'appareil peut être chargé en agar-agar liquide avant l'utilisation; cet appareil est caractérisé en ce que des repères sont prévus adjacents auxdits canaux pour permettre une mesure visuelle directe, de l'effet d'une substrance d'essai sur la croissance d'un microorganisme sur ledit agar-agar, lorsque ladite substance d'essai a pu se diffuser le long dudit canal à partir d'un point bien déterminé d'application, pour constituer un gradient de concentration de ladite substance le long dudit canal.
